adapted to be readily folded along certain lines and particularlyadapted for use in a foldin conch, whereby when said mattress ishorizontally extended, it will have a substantially unbroken surface,and when folded, the surfaces of the sections'at opposite sides of thefold will be substantially at right angles to each other close to thefold;

and to provide a mattress of the usual box type, in which the boxappearance is maintamed, although it is capable of being read ilyfolded.

An illustrative embodiment of this invention is shown in theaccompanying drawings,

in which Figure 1 is a perspective View of a box mattress constructedaccording to this invention. Fig. 2 is a sectional view of the same,taken on the line A-A of Fig. 1. Fig. 3 is a corresponding section,showing the mattress in position upon a folding couch when the latter isin its folded or sofa position. Fig. i is a fragmentary section on theline B-B of Fig. 1..

lln the construction shown in the drawings, the mattress is of the usualbox type, and comprises upper and lower coverings 1 and 2, spaced apartby edge strips 3. Before the mattress is filled with the paddingmaterial 4, the upper and lower coverings 1 and 2 are stitched orotherwise fastened together at 5 along the lines on which the mat tressis to be folded. This stitching extends throughout the greater part ofthe length of the mattress, but terminates a short distance from theends thereof. The padding material is now filled in from the ends beforethe sewing of the edges of the end strips 3 is completed. Between eachend of the lines of stitching 5 and 6 and the ends of the mat-tress,there is a marginal portion 7, which is filled to correspond to the fullthickness of the mattress, thus preserving the box like contour, as maybe seen from' Fig. 1. When the mattress is finished, the

lines of stitching 5 and 6 divide it into tions which in c'fibct arehinged together, and which can be readily folded at right angles to eachother. The-marginal portions i, being comparatively narrow, do notprevent the free folding of the mattress.

This mattress is particularly adapted for use in folding couches, eitherof the type where the sides fold down against the frame, orof the typewhere one side folds down and the other up.

Fig. 3 of the drawings shows the mattress in position on the davenportstyle of folding couch, in which the side 8 is folded down against theframe, and the side 9. is folded up to form a back. This arrange mentavoids the common fault of this type of couch when fitted with anordinary muttrcss, namely that when a person sits upon the seat section,there is a strain directed to the back section, which distorts it andrenders it both uncomfortable andunsightly. The construction shown inthe drawing gives a more elegant appearance to the couch when a cover isthrown over the mattress, since it insures sharp bends at the folds, andavoids bunching of the mattress, and the uncomfortable rounded bends oflarge radius occurring when the ordinary mattress is used.

ll amaware that mattresses have been made with their opposite facesstitched together by rows of stitches extending across the entire lengthor breadth of the mattress, but such sectional mattresses areobjectionable for the reason that edges of the sections become roundedand form wide gaps in the surface along the rows of stitching whereextended, rendering the mattress uncomfortable for use as a bed, andwithout the desired hoxlihe appearance. Such a divided mattress is alsoincapable of preserving a sharp angular fold adjacent to the outer facesof the sections, as illustrated in Fig. 3.

I claim 1. A box mattress, having a crease extending partially across itto provide folding sections, said crease being formed by bring I ingtogether and securing. the upper and lower coverings throughout aportion of their length, and means for preserving the box shape of themattress at the endsof the creases, across the foldin sections.

2. A folding mattress, avin a crease extendin artially across it, saicrease being f0 y drawing the opposite coverings -'of said mattresstogether tooform said heattress into folding sections and beingterminated inward of the ends of said mattress.

. v3. A folding mattress, having a crease extending partially across it,said crease being formed by drawing the opposite interme diate portionsof the coverings of said mattress together and being terminated inwardof the ends of said mattress, and said matings being stitched togetherat intermediate portions only to form a crease in the mattress extendingpartially thereacross when said coverings are stuffed, said side stripsbeing continuous and of substantially full width across the ends of saidcrease, and means for supporting said side strips at the ends of thecreases to preserve the box shape of the mattress at those points. 5. Afolding mattress, comprising a plurality of integral sections, saidsections being formed by stitching together the coverings of saidmattress along a plurality of parallel lines extending partiallythereacross, said stitching terminating inward of each end of saidmattress, and said mattress having continuous uncreased marginalportions extending across the ends of said creases for the purposespecified.

Signed at Chicago this 30th day of December 1910.
